Description

Thoracolumbar body surface positioning device suitable for multiple surgical approaches

Technical Field

The utility model relates to the field of medical equipment, especially a chest lumbar vertebrae body surface positioner suitable for multiple operation approach.

Background

Most thoracolumbar positioners are mainly used for body surface positioning of the thoracolumbar posterior path at present and mainly used for judging the positions of a vertebral body and part of puncture points (such as intervertebral foramen and vertebral pedicle) of an operation. In recent years, minimally invasive awareness of the spine has been strengthened, and lateral approaches such as OLIF, DLIF, XLIF, CLIF, etc.; is more and more widely used in clinic. The lateral approach requires that the patient is in a lateral decubitus position, X-ray irradiation is usually performed when the incision position is confirmed, the middle section of the responsible intervertebral space is confirmed on a lateral plate, and the surgical incision is confirmed according to the projection of the midline of the vertebral body on the body surface (the Olif surgery needs to be confirmed 4-10cm before the projection point of the midpoint of the intervertebral space on the body surface, specifically according to the body type of the patient and each target vertebral body). However, because the human body surface has no obvious reaction to the X-ray, at present, a metal or polymer material net rack is often adopted to be directly erected on the human body surface, and then the initial or terminal position of the incision is marked according to the relation between the coordinate position on the net rack and the projection position of the target point to be positioned on the body surface. Because the metal net rack can not be completely applied to the body surface, the requirement of designing the incision directly according to the requirement of the incision designed before the operation and the projection point of the target body surface after the target body surface is positioned can not be met, and particularly, in the Olif operation, large errors are easy to occur.
